Electrical parameters Filament voltage: 5V Filament current: 14.5A The maximum instantaneous filament current: 22A Magnification factor: 130 Transconductance: 15mA / V Electrode capacitance: Anode - the GRID: 4.1pF Cathode - the GRID: 7.4pF Anode - Cathode: 0.07pF Mechanical properties: Quality: (approximately) 0.25Kg (F) Installation: vertical, anode terminals up Cooling: natural cooling Shell and tube maximum temperature: 225 ° C Anode sealing at the maximum temperature: 225 ° C The core columns to seal the access at the highest temperature: 200 °C Maximum ratings
The maximum anode DC voltage: 4KV Maximum Anode DC Current: 350mA Maximum anode dissipation power: 500W Maximum GRID power dissipation: 20W In typical operation: class C telegraph Filament voltage: 5V Anode DC voltage: 3.5KV GRID DC bias voltage:-75V Anode DC Current: 300mA GRID DC current: 115mA Anode output power: 850W Note: generally under matched load can be naturally cooled, but the equipment must be well ventilated, if in a non-matched load, high pressure, high-frequency conditions required for forced air cooling, ventilation should be through the outlet from the tube at the bottom of under the previous air.
